1. Project Preparation / Requirement GatheringCollect requirement thru interviews with Business teams /Core users / Information Leaders .Study & analyze KPI 's (key figures) of Business process .Identify the measurement criteria's (Characteristics).Understand the Drill down requirements if any.Understand the Business process data flow if any .Identify the needs for data staging layers in BW (i.e need for ODS if any)Understand the system landscape .Prepare Final Requirements Documents in the form of Functional specifications containing :Report Owners,Data flow ,KPIs ,measurement criterias,Report format along with drilldown requirements .

2. Business BlueprintCheck Business content against the requirementsCheck for appropriateInfo Objects - Key figures & CharactersCheck for Info cubes / ODSCheck for data sources & identify fields in source system

Identify Master datadocument all the information in a file follow standard templatesPrepare final solutionIdentify differences (Gaps) between Business Content & Functionalspecification. propose new solutions/Developments & changes if required at different levels such as Info Objects ,Info cube , Data source etc . Document the gaps & respective solutions proposed follow standard templatesDesign & DocumentationDesign the ERD & MDM diagrams for each cube & related objectsDesign the primary keys/data fields for intermediate Storage in ODSDesign the Data flow charts right from data source up to Cube .Consider the performance parameters while designing data modelsPrepare High level / Low level design documents for each data model.--- follow s

tandard templatesIdentify the Roles & Authorizations required and Document it follow standard templatesfinal review of design with core BW users .Sign off the BBP documents

3. RealizationCheck & Apply Latest Patches/Packages ...in BW & R/3 systems.Activate/Build & enhance the cubes/ODS as per data model designs...maintain theversion documents .Identify & activate Info objects / Master data info sources / attributes ,prepare update rulesAssign data sources .prepare transfer rules , prepare multi providers . prepare
